To all rwhom t may concern.'

Be it known that I, JAMES A. PARK, a citizen of the United States, and a residentof Passaic, county of Passaic, and State of New Jersey, have invented certain new and i useful Improvements in Brackets, of which the following is a specication.

Y My invention relates to brackets; and, while it may be embodied in constructions adapted for various purposes, it is more particularly applicable to adjustable supporting brackets for chairs, desks, tables, and the like.

Objects of the invention are to provide a device of the character described which shall be simple and certain in operation; whose members shall be compactly and conveniently arranged; which shall be adapted to be used with a variety of articles, such as chairs, desks, tables, stoves, sewing machines, and the like; whose members shall L be inconspicuous both in operation and when at rest; and which shall be simple and cheap and yet durable inv construction. These and other objects of the invention will in part be obvious and in part be more fully set forth in the following description.

The invention consists in the novel parts, arrangements, combinations, features of construction, and improvements herein shown and described.

The accompanying drawing, which is referred to herein Yand forms a part hereof, illustrates one embodiment of the invention, the same serving in connection with the description herein to explain the principles of the invention.

Of the drawing: Figure l is a side elevation of an adjustable supporting bracket constructed in accordance with certain features of my invention and being shown as used in connection with a chair; Fig. 2 is a sectional plan view of the same taken on the line 2 of Fig. l; and Fig. 3 is a vertical sectional view taken on the line 3 of Fig. 1.

An adjustable supporting bracket constructed in accordance with certain features of my invention comprises in combination, a support-ing element, a supported element, and a connecting element pivoted to both said rst two elements on axes which are disposed at an angle to each other. An adjustable supporting bracket constructed in accordance with certain other features of my invention comprises in combination, a supporting element comprising a plurality of members, a rod pivotally mounted in said members, a supported element, a rod pivot- 2 ally mounted in said supported element and i disposed at an angle to said first named rod, and a connecting element comprising a plurality of members between said first two elements. According to a preferred embodiment of the invention, the angle between said pivot rods is substantially forty-five de- Qgrees. In accordance with my invention, f the supporting element of the bracket may be mounted upon a piece of furniture or other article of manufacture, as, for eX- i ample, a stove or sewing machine, the same constituting a base, and the bracket serving to movably support a leaf or other element ,in operative relationrto said article. These and other features of the invention will be ,more fully explained in the following detscription.

Referring now in detail to the drawing, 2 the embodiment 0f the invention illustrated l is shown" as used in connection with a chair l having a desk or table leaf 4. It is the -purpose of the invention, as used with the 1 chair, to furnish a convenient and satisfactory means for bringing the leaf 4 from its :inoperative position, shown by the dotted lines in Fig. l, to its operative position on vthe arm of the chair, the usefulness of the ;leaf 4 in this latter position being obvious. To accomplish this result suitable swinging connections are provided between the chair l and the leaf 4. While these connections may be made in various ways, preferably and as shown, a supporting element is fastened to the side of the chair. While this supporting element may be fashioned in a variety of ways and may be located in different places on the chair, it is shown as comprising a member 5 fastened to the chair at or near the rear of the arm 7. Preferably and as shown, also, an additional supporting `member 6 is secured to the seat of the chair, preferably at the inside thereof. The =members 5 and 6 are provided with bearings in which is pivotally mounted a rod 8. The members 5 and 6, also, are preferably so constructed and secured to the chair that the rod or pivotal axis thereof is arranged at an angle of about forty-live degrees from the vertical.

A supported element is also provided, to which is secured the leaf 4. While this supported element may be variously formed and lmay comprise any desired number of members which may be disposed in any desired positions on the leaf, preferably and as shown, it comprises a member 9 having bearings in which is pivotally mounted a rod l() so disposed that the angle between it and the rod 8 is substantially forty-tive degrees.

The leaf fle, when in operative position on the arm of the chair, may be removably secured thereto in any desired way. As shown, this is accomplished by providing an extension l1 to the supporting member 9, a recessed portion serving to engage the arm of the chair, and the extension ll having a suitable slant to enable the leaf to move smoothly into operative position.

1While any desired connections may be provided between the supporting element and the supported element, in the preferred embodiment of the invention illustrated in the drawing a connecting element is provided, comprising a member 13, pivotally mounted upon the rods S and l0 near the rear ends thereof, and, preferably, also, a member 14C, pivotally mounted upon the rods 8 and l0 at the forward ends thereof, the member 1d being bifurcated at its lower end to give it greater stability.

As will be apparent from the foregoing description, the operation of the device is very simple. The rod 8 being disposed at an angle of about forty-live degrees to the leaf and its rod 10, the leaf describes an arc of ninety degrees in its path of travel from the position at rest, shown by the dotted lines in Fig. l, to its operative position on the arm of the chair, and at the same time the leaf may be turned on its axis i0. Furthermore, it will be apparent that as the supporting member (3 is atlixed to the inside of the scat of the chair, and the rod 8 is in close proximity to the side of the chair, and as the leaf is turned on the rod 10, as described, the leaf 4, when in its position of rest, will hug closely the side of the chair and not approach so far forward as to pro" ject beyond the leg of the chair. It will be apparent also that the swinging operation of the device can be effected by an apparatus having only a single supporting member. Furthermore, although the best results are secured in the particular adaptation of the device illustrated by parts proportioned and disposed as shown, it will be apparent that the number and extent of the members of the several elements may be varied as desirod.

It will be seen that by reason of the construction described, a form of adjustable bracket is provided which is cheap to manufacture; simple and durable in construction; efficient in operation; not apt to get out of order; whose members are compactly arranged and inconspicuous; and which may be used with a great variety of objects, as

chairs, desks, tables, stoves, sewing machines, and the like. Other advantages will be apparent to those skilled in the art.

My invention in its broader aspects is not limited to the precise construction shown and described nor to any particular construction by which the same has been or may be carried into effect, as many changes may be made in the details of the parts without departing from the main principles of the invention and without sacrificing its chief advantages.

I claim:

l. A bracket having in combination, a supporting element comprising a plurality of members, a supported element, and a connecting element comprising a plurality of members pivoted to said supporting and supported elements, the axis of the pivotal connections of the supported element being at an angle to the axis of the pivotal connections of the members of the supporting element.

2.
